Class Information
Number: 585/612
Name: Chemistry of hydrocarbon compounds > Unsaturated compound synthesis > Diolefin product > From nonhydrocarbon feed > Halogen-containing feed using extraneous nonhydrocarbon agent
Description: Subject matter wherein a feedstock compound contains fluorine, chlorine, bromine, or iodine and part or all of the synthesis takes place in the presence of a material which chemically affects the synthesis by promoting, retarding, etc., but which does not form a part of the desired product and is, at least in theory, separable from the desired reaction products. The agent may be a catalyst, solvent, etc., and is inorganic or is an organic material containing other elements than carbon and hydrogen.
